More Power and Better Performance. Improve the power and performance of your 2013-14 Shelby GT500 Mustang with a SCT Rev-X Tuner that includes (3) Brenspeed Custom Tune Files. When your Mustang rolled off the assembly line, Ford programmed it to cater to the needs of the daily driver, not the performance enthusiast who adds aftermarket bolt-on modifications in the search for more power. So, if your Mustang is bone stock or if you have added a cold air intake, throttle body, exhaust or other bolt-on performance upgrades, you'll need a custom tune to see the full power potential that these aftermarket mods can make.

Three Custom Brenspeed Tune Files. When you order a Rev-X Tuner by SCT, you aren't just getting a tuner. You're getting the tuner and 3 dyno-tested custom tune files that are written specifically for your Mustang and your particular modifications by a Brenspeed calibrator. Brenspeed tunes must pass a rigorous list of specifications through racing, street driving, and dyno testing before they are released to the public. By optimizing cam timing curves, spark curves, and air/fuel tables, a Brenspeed Custom Tune will squeeze out the extra power Ford left on the table. You will receive 3 tune files including (1) Low Octane Street Tune, (1) High Octane (up to 93) Street Tune, and (1) High Octane (up to 93) Race tune.

WiFi Updates and Cloud Tuning. The Rev-X Tuner by SCT is Wi-Fi capable meaning it will always be up to date. Once setup with your Wi-Fi password, the Rev-X will download the latest firmware updates via the internet. Besides firmware updates, your Rev-X can also download your custom tune files via the cloud, reducing the hassles of transferring files from your PC to your Rev-X device.

Data Logging and Monitoring. The Rev-X Tuner by SCT makes it easy to read the Built-In Data Logging and/or the Real Time Data, so you can view popular sensor data such as EGT, Air/Fuel Ratio or any other 0-5 Volt source. You can even customize the monitoring capability of your Rev-X using device's free Livelink software.

Diagnostics Tool. The Rev-X Tuner can also be used as a diagnostic code reader. Save yourself hundreds of dollars each year by reading and clearing your own Diagnostic Trouble Codes (DTCs) rather than paying a dealer to do the same. It's as easy as a few simple steps.

Easy to Load; Easy to Restore. When you load your custom tune on the vehicle, the tuner automatically stores your vehicle's factory settings. To return the vehicle to its factory settings, just plug the tuner back in, select the option to restore the factory settings, and you're done. This is ideal for visiting dealerships for warranty work.

Application. This Rev-X Tuner by SCT that includes 3 Custom Brenspeed Tunes is specifically designed for 2013-2014 Shelby GT500 Mustang models equipped with the supercharged V8 engine that are stock or running basic bolt-on modifications such as a Cold Air Intake, Throttle Body and/or Full Exhaust System. Aftermarket camshafts, aftermarket and/or ported Heads, or aftermarket intake manifolds are not supported.

Please Note. After you order Brenspeed's sales department will e-mail you to find out about your current modifications if any, your Mustang in general, and other information so we can develop your custom tunes.

**Please Note: The SCT Rev-X Tuner ships blank from AmericanMuscle, the custom tune files will be emailed directly to the end user within 2-3 business days from Brenspeed.

This product will not ship to addresses in California due to state regulations. Additionally, support will not be provided for tuning for California residents.

Since day one it has been all about being a “true blue gal”. I can proudly say that every single one of my family members has owned a mustang at one point or another! Growing up I was either camping, at the farm, or at the racetrack. I’ve always been around some sort of mustang and have learned that...
